The second bass pass filter(150) filters a low level output from the coupler(148) as a setting band. The sixth amplifier(152) amplifies a signal output from the second band pass filter(150) at a certain level. A detector(154) detects a signal output from the sixth amplifier(152). A comparator(156) compares the output signal of the detector(154) with a predetermined reference signal and generates an attenuation control signal according to the result value. An attenuation module(158) attenuates or outputs an IF(Intermediate Frequency) output from the fourth low pass filter(140) according to the attenuation control signal output from the comparator(156).
